针对水轮机调节系统PID参数辨识问题，作者在VC++6.0环境下，使用c语言，编写PID参数参数辨识程序，结果表明，该程序能够辨识出Kp,Ki,Kd三个参数，满足调节系统的误差要求。(Turbine regulating system for PID parameter identification problem, the authors VC++ 6.0 environment, using c language, the preparation of PID parameters of parameter identification procedures, results show that the program can identify Kp, Ki, Kd three parameters to meet conditioning systems error requirements.)

通讯录中的每一个信息包括姓名（规定字节数为15个）、电话（规定字节数为15个）和工作单位（最大字节数为30个）等信息。(Each information including the name of the mail list ( specified byte number 15 ), phone ( specified byte number 15 ) and work units ( the maximum number of bytes to 30 ) and other information.)

WORD VB 二次编程，实现题库管理与自动出卷功能。(The WORD VB quadratic programming, question bank management, and automatic volume. )

说明：  下面是一个结构体声明： struct box { char maker[40] float height float width float length float volume } a. 编写一个函数，按值传递box结构，并显示每个成员的值 b. 编写一个函数，传递box结构的地址，并将volume成员设置为其他三维长度的成绩。 c. 编写一个使用这两个函数的简单程序 (Here is a structure declaration: struct box {char maker [40] float height float width float length float volume } a. Write a function that is passed by value box structure, and shows the value of each member b . to write a function, passing the address box structure and volume settings for the other three members of the length of the results. c. use these functions to write a simple program)

输入一个矩阵，可以求得该矩阵的逆矩阵，内附解释说明(Enter a matrix, you can obtain the inverse matrix, containing an explanation)

此系统由VC++ 6 0 MFC开发而成,主要实现一些基本的界面操作,如画笔画刷,文字改变字体颜色,以及时钟显示和小型购物系(This system is developed by VC 60 MFC. It mainly implements some basic interface operation, such as brush, text changing font color, clock display and small shopping department.)
